- 1 Claim. (Cl. 126-231) This invention relates to a supporting devicefor attachment to a Bunsen burner.

An object of the invention is to provide a novel supporting device fordetachable attachment to a Bunsen burner so as to support selectivelyvarious tools or instruments upon a Bunsen burner for heating a portionof such toolor instrument in the flame of the burner.

Another object of the invention is.to provide a novel supporting devicefor detachable attachment of a Bunsen burner for supporting variousinstruments or tools thereon and in such a position relative to theburner that waxes, and other materials, which may adhere to theinstrument will not, when melted under the heat of the burner flame,drop into the burner itself or into the barrel thereof.

Still another object of the invention is to provide a supporting devicefor attachment to Bunsen burners and which is especially adapted for useby dentists and dental technicians in holding various dentalinstruments, such as are used in forming or working wax castings, so asto beat such an instrument readily in the flame of a Bunsen burner whileat the same time, preventing any wax or like material which may beadhered to the instrument from falling into the burner or into thebarrel thereof when melted by the heat of the burner flame.

Other objects will appear hereinafter.

In the drawing:

Fig. l is an elevational view, partly in section, illustrating a typicalembodiment of the invention as applied to a Bunsen burner, a part of thewall of the barrel of the Bunsen burner being broken away to illustratethe construction and use of the new supporting device;

Fig. 2 is a front elevational view of the new supporting device;

Fig. 3 is a side elevational view of the new supporting device;

Fig. 4 is a centrally vertical sectional view of the new supportingdevice on line 4-4 in Fig. 2; and

Fig. 5 is a sectional plan view of the new supporting device on line 5-5in Fig. 1.

A typical embodiment of the new supporting device is illustrated in thedrawing, wherein it is generally indicated by 141 and is shown a beingdetachably mounted upon the tubular barrel 1.1 of a Bunsen burner 12 ofconventional design.

The new Bunsen burner attachment or supporting device includes agenerally channel-shaped body 13 which is preferably formed of suitableferrous, metallic material, and this body 13 has a pair of resilientclamping arms 14 formed integrally therewith one at each side thereof.These resilient clamping arms 14 are adapted to releasably grip or clampthe side wall of the barrel 11 of the Bunsen burner 12 so as to hold thenew supporting device 10 detachably in position thereon.

The new Bunsen burner attachment or supporting device it) has a latchingtongue 15 formed integrally therewith and struck therefrom and thislatching tongue 15 is adapted to latchingly engage in the centralopening or gas-air mixture outlet 16 at the top of the burner 2,764,146Patented Sept. 25,, 1956 2. barrel 11 as shown in Fig; 1, so as to holdthe new Bunsen burner attachment or supporting device securely inposition of use upon the barrel 11 of the Bunsen burner 12-.

The new Bunsen burner attachment or supporting device 10 also-includes alaterally and generally horizontally extending supporting arm 17 whichis formed integrally with the upper end portion of the body13; and thislaterally and horizontally extending supporting arm 17has an upwardlyinclined tool receiving or instrument receiving portion 18 which isprovided at theupper end thereof with a pair of resilient gripping arms19 which are formed integrally therein. As best shown-in Fig. 2 the toolreceiving and instrument receiving extension 18. extends upwardly at anacute angle relative to the laterally and generally horizontallyextending arm 17, and this extension 18 has a pair of tool receivingrests or prongs 26 formed therein below the resilient gripping arms 19.

In the use of the new Bunsenburner attachment or supporting device Iii,the same may be detachably mounted upon the barrel 11 of aBunsen burner12 by slipping the resilient gripping arms 14 about the burner barrel 11and projecting the latchingv tongue 15 downwardly through the centralopening 16 or gas-air outlet at the upper end portion of. the barrel 11so that the new Bunsen burner attachment or supporting device 101 willthereupon be mounted in position of use, as shown in Fig: .1.v Tofacilitate this resultth'e resilient gripping. arms-14:and the. body13ofthe new Bunsen.burnerxattachment areso formed that the resilientgripping arms 14will bespread slightly whenplacedtupon theburnerbarrelll whiclris somewhat larger inv diameter than the. diameterof the, generally channel-shaped body 13. When so disposed, the newBunsen burner attachment or supporting device It) will have thelaterally and generally horizontally extending supporting arm 17 and itsupward extension 18 positioned as shown in Fig. 1, whereupon any desireddental or other tool or instrument 22, which the user may desire to heatin the flame 23 of the Bunsen burner 12, may be inserted between theyieldable gripping arms 19 so as to rest on the inclined upwardextension 18 of the horizontally extending supporting arm 17 and in therests or prongs 20, as shown in Fig. 1, with a portion of the tool orinstrument 22 projecting into the flame 23 of the Bunsen burner 12.

After a portion of the tool or instrument 22 has thus been heated, thetool or instrument 22 may be readily removed from the new Bunsen burnerattachment or supporting device 10 by simply pulling it out of positionbetween the resilient gripping arms 19, whereupon the new Bunsen burnerattachment or supporting device 10 may be readily removed from thebarrel 11 of the Bunsen burner 12 by raising it slightly so as to removethe latching arm 15 from the central outlet opening 16 at the top of thebarrel 11 and then sliding the body 13 from the burner barrel 11.

As shown in the drawing, the upwardly inclined supporting arm 18 has anelongated slot or opening 21 formed therein, below the tool receivingrests or prongs 20, and this elongated slot or opening 21 makes itpossible for the user of the new Bunsen burner attachment to support atool or instrument in a generally horizontal position, during theheating operation by projecting a portion of the tool through the slotor opening 21 into the flame 23 with a portion of the tool or instrument22 resting on the upwardly extending supporting portion 18.

It will be noted that the arrangement of parts in the new Bunsen burnerattachment, include the laterally and generally horizontally extendingarm. 17 at the inclined upward extension 13, thereby prevents any wax orother material which may be disposed in the tool or instrument 22 fromdropping into the burner 12 or into the barrel 11 thereby when melted bythe heat of the flame 23 of the burner.

It will thus be seen from the foregoing description, considered inconjunction with the accompanying drawing, that the present inventionprovides a'new and improved Bunsen burner attachment or supportingdevice having the desirable advantages and characteristics andaccomplishing its intended objects including those herein just pointedout and others which are inherent in the invention.
